Our department uses the Impalas. We were going to go with Chargers but we use a federal grant for vehicles and the car has to be made in the United States. The Chargers are built in Mexico. As you stated, the Caprice is Australian so that's out. We have 1 Taurus, but in 30k miles its been out of service 8 times. Including 6 weeks back to ford after the AWD ate itself. Now the trans is going.
